Import Debian changes 1.12.2-0ubuntu3
network-manager (1.12.2-0ubuntu3) cosmic; urgency=medium
* debian/rules:
- use --with-libnm-glib, the default reversed since that's a legacy
library but we still need it for unity-control-center
network-manager (1.12.2-0ubuntu2) cosmic; urgency=medium
* debian/patches/git-newglib-test.patch:
- backport upstream commit to fix the tests with the new glib
network-manager (1.12.2-0ubuntu1) cosmic; urgency=medium
* New upstream version
* d/p/libnm-register-empty-NMClient-and-NetworkManager-when-loa.patch,
d/p/e91f1a7d2a6b8400b6b331d5b72287dcb5164a39.patch,
d/p/git_thunderbolt_connect.patch:
- removed, those changes are in the new version
* Backport Debian changes
* Update symbols file for libnm0
* Enable iwd support
* Drop version requirements when oldstable ships a newer version
* Drop dh_strip override, the dbgsym migration is done
* Rebase patches
* Make sure the example server.conf is actually installed
* Update install path for plugins, it now includes a version number
* Drop libnl3 build dependency.
Upstream has copied the code directly from libnl3 for the few functions it
needs with a few small modifications.
* Drop libiw build dependency.
Hasn't been needed for a long time and was simply a left over from older
releases.
* Bump Standards-Version to 4.1.5
* Fix compile error due to NM_AVAILABLE_IN_1_12_2 macro (Closes: #905372)
